Description
Technical field
A kind of sealing structure of rotary drill rotating inlet device is the utility model is related to, belongs to surface mine rotary drill
The rotating inlet equipment technical field of machine.
Background technology
Rotary drill is the main equipment of surface mine digging, and drill process needs to use gases at high pressure and water, high pressure gas
After body and the rotated inlet duct of water mix, entered in drilling rod, coordinated by the revolving hollow spindle in rotary gear box
Drill bit completes drilling operation.
At present, the sealing of rotary drill rotating inlet device is formed close using stretchy nylon mechanical seal and support plate
Seal structure.Because operation field condition is more severe, the stretchy nylon mechanical seal of rotation portion, support plate and revolving hollow spindle are easy
Sustain damage, higher, the higher fault rate of the failure for causing rotating inlet device race wind to metal run out, have a strong impact on surface mine digging
The safety of operation and production.Therefore, how to reduce the fault rate of rotating inlet device, turn into the reality that rotary drill faces
Problem.
Utility model content
The utility model purpose is to provide a kind of sealing structure of rotary drill rotating inlet device, substitutes original elasticity
Nylon mechanical seal and the sealing structure of support plate composition, it is ensured that its sealing and durability, solve present in background technology
Problem.
The technical solution of the utility model is：
A kind of sealing structure of rotary drill rotating inlet device, comprising the sealing of Y types soft framework, sealing punching press oil filler point,
Steel bushing, determine ring and revolving hollow spindle, determine ring and be fixed on revolving hollow spindle, steel bushing, which is welded on, to be determined on ring, and multiple tracks Y type soft frameworks are close
Envelope is embedded in steel bushing, and steel bushing is provided with sealing punching press oil filler point, and multiple tracks Y types soft framework is sealed by sealing punching press oiling pore pressure
Tightly on revolving hollow spindle.
The Y types soft framework is sealed into four, is evenly arranged on steel bushing.
The center line of sealing punching press oil filler point and the central axis of revolving hollow spindle on the steel bushing are arranged.
It is described to determine ring set on revolving hollow spindle.
The beneficial effects of the utility model are：Using Y types soft framework seal, substitute original stretchy nylon mechanical seal and
The sealing structure of support plate composition, strengthens the sealing and durability of rotating inlet device, reduces repair density, shorten
Maintenance time, extend the service life of equipment.It is simultaneously easy to use, securely and reliably.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In figure：Y types soft framework sealing 1, seal punching press oil filler point 2, steel bushing 3, determine ring 4, revolving hollow spindle 5.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1, a kind of sealing structure of rotary drill rotating inlet device, Y types soft framework sealing 1, sealing are included
Punching press oil filler point 2, steel bushing 3, determine ring 4 and revolving hollow spindle 5, determine ring 4 and be fixed on revolving hollow spindle 5, steel bushing 3, which is welded on, determines ring
On 4, multiple tracks Y types soft framework sealing 1 is embedded in steel bushing 3, and steel bushing 3 is provided with sealing punching press oil filler point 2, multiple tracks Y type soft frameworks
Sealing 1 is pressed on revolving hollow spindle 5 by sealing punching press oil filler point 2.
In the present embodiment, revolving hollow spindle 5 is stepped hollow shaft, determines ring 4 and is enclosed on revolving hollow spindle 5, steel bushing 3 welds
It is connected on and determines on ring 4, the center line of sealing punching press oil filler point 2 on steel bushing 3 is arranged with the central axis of revolving hollow spindle 5, Y types
Soft framework sealing 1 is four, is evenly arranged on steel bushing 3.Four Y types soft frameworks sealing 1 is compressed by sealing punching press oil filler point 2
On revolving hollow spindle 5, the sealing structure of rotary drill rotating inlet device, good airproof performance are formed.
